IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!
Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.
We have compiled some common reasons and troubleshooting tips at:
https://numpy.org/devdocs/user/troubleshooting-importerror.html
Please note and check the following:
* The Python version is: Python3.9 from "C:\Users\sh198\Anaconda3\envs\rl\python.exe"
* The NumPy version is: "1.21.4"
and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.
Original error was: DLL load failed while importing _multiarray_umath: 指定されたモジュールが見つかりません。
- 問題ない仮想環境もある
- VSCodeに代わりanaconda powershellからは問題が起こらない
この現象が起きる仮想環境の共通点
- _multiarray_umath.cp39-win_amd64.pydが…/envs/（仮想環境名）/Lib/site-packages/numpy/coreのなかに存在する
- pythonとnumpyのバージョンは関係なさそう
自分で試したこと
悔しいから再インストールとかしたくない
vscodeとpowershellでそれぞれ$PATHを確認する．
powershell側は…/envs/（仮想環境名）/Lib/site-packagesを含んでいるのに対して，vscode上ではそれが含まれていない．
